Unanswerable questions

After my unsuccessful attempt to try out the (broken) Sony e-reader on display in my local Waterstones at the weekend* and observing the notice on it to the effect that you might as well not bother ordering one as they are backed up for the next decade or so with requests, I am moved to ask:

Is the Sony e-reader the new Wii Fit?

Although my question is made with the availability issue in my mind, I also wonder I have another subconscious agenda, to do with the relationship of these "tools" with the real world. You don't need an electronic device to read any more than you need an automated weighing machine hooked up to your TV to do exercise.

Yes I know that there are lots of good uses of an e-reader in terms of storage capacity, baggage restrictions, sheer tonnage of printed books, sample chapters and so on. And I know that it might be more fun watching your Mii overtake Harry, Ron, Hermione, Voldemort and Dork's (don't ask) Miis than getting muddy on a lonely circuit of the local park. On the other hand, couldn't we have an accessible new technology that is so popular you can't buy it but also that does something you couldn't do before? Teleport you to work in the morning and back at night, for example?

And here is another question:

Is the "bag for life" the new plastic carrier bag?

I have lost count of the number of tasteful hessian bags I have generously been given in the past year or so. None of them has handles long enough to carry on a bike (with drop handlebars and no basket). What can I do with them all that is ecologically acceptable? At the moment they are all in a cupboard with hundreds of plastic carrier bags (which arrive in the house at a rate of knots despite my never using one when I go shopping, armed with my ancient canvas long-handled bag or a rucksack).

*Footnote: I have had a generous offer to try out a friend's Sony e-reader, by the way, so my curiosity will soon be satisfied. On the basis of the broken one in Waterstones, I suspect I shall continue to observe vicariously rather than to attempt to purchase and participate.
